In addition to the treacherous driving conditions through Thursday evening, the snow and sleet, combined with wind gusts up to 35 miles per hour, could cause power outages during the height of the Nor'easter, which is projected to result in higher accumulations than earlier predictions.

A Winter Storm Warning is now in effect for the entire region until 10 p.m. Thursday.

Snow/sleet accumulations of 2 to 5 inches are now expected south of I-287 and the Merritt Parkway and 3 to 6 inches inland. Western areas north of I-84, including Dutchess, now could see between 8 and 12 inches of snowfall.

There is still uncertainty with the projection amounts, however, because the extent and timing of snow mixing with sleet are unclear. The northern areas with less mixing are expected to see the most accumulation.

The wintry mix will continue for the entire region through around 11 p.m. Thursday before changing over to rain. Areas farther north will see freezing rain and some sleet and snow overnight through early morning, meaning school delays and even closures are possible farther north on Friday.

The entire region will see rainfall into Friday morning before gradual clearing in the late morning and early afternoon as the high temperature climbs into the mid-40s.
